NOTES:
6. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
7. Typical values are for TA = +25°C and VIN = 3.3V.
8. LSB = I V255 - V1I / 254. V255 and V1 are the measured voltages for the DCP register set to FF hex and 01 hex respectively.
9. DNL = I Vi+1 - Vi I / LSB-1, i ∈ [1, 255]
10. ZS error = (V1 -VMIN) / LSB. VMIN = (VAVDD*R2) * [1-254*R1/(255*20*RSET)]/ (R1+R2).
11. FS error = (V255 - VMAX) / LSB. VMAX= (VAVDD*R2) * [1-0*R1/(255*20*RSET)]/ (R1+R2).
12. Established by design. Not a parametric spec.
13. Boost will stop switching as soon as boost output reaches OVP threshold.
14. Compliance to limits is assured by characterization and design.
